Experiments in Microwave Technology with Code Implementation

This article introduces experimental procedures and simulation models related to microwave technology. In microwave engineering, microstrip lines, striplines, power dividers, and stub matching circuits are essential components. Microstrip lines serve as transmission lines in microwave integrated circuits, widely adopted due to their low cost, manufacturing ease, and convenient installation. When implementing microstrip line simulations, engineers typically use parameter calculation algorithms to determine characteristic impedance and phase velocity based on substrate properties and physical dimensions. Striplines represent an advanced form of microstrip lines that enhance bandwidth while reducing transmission losses. Simulation models for striplines often employ finite-element analysis methods to account for electromagnetic field distribution between ground planes. Power dividers are components that distribute signals to multiple branches, supporting high-power and broadband applications. Their design commonly involves even-odd mode analysis algorithms and impedance transformation calculations to achieve optimal power splitting ratios. Stub matching circuits facilitate microwave signal transfer between different circuit sections, making them crucial in microwave circuit design. These matching networks typically utilize Smith chart-based optimization algorithms and transmission line theory to achieve impedance matching at target frequencies.
